A minor stability update for the Sprint HTC EVO 4G brought some improvements to WiFi speeds and eliminated a screen grounding issue whereby if a user held the phone in the wrong way or placed the phone on a table, the screen may not respond to touch. However, after rolling out the update, Sprint and HTC have decided to stop the updates temporarily due to a handful of user reports that the update had bricked their devices. According to a Sprint statement to MobileCunch, the companies are investigating the matter before continuing with the OTA update process:

While the vast majority of consumers successfully downloaded and installed the most recent HTC EVO 4G software update, we have received a handful of reports from customers having some issues with the update. In light of this, HTC and Sprint have decided to temporarily halt distribution of this software release until we can investigate further. We expect to be able to resume software updates shortly.
